A Starry Question at the Check-out Counter

Are Stars Scary?

Let’s take a break from black holes and come home to Earth for a bit. A while back I was in line at a store and was talking to the person ahead of me about what I do. (I was wearing a Hubble Space Telescope t-shirt, which tipped her off, I suppose, that I might be one of THOSE people…)

She asked me if there was anything in the sky that could scare kids. She wanted to take her 8-year-old son to the Museum of Science to look through a telescope, but didn’t want him to get scared. I asked her if he was easily scared and she said that he wasn’t. So I asked what she was worried about. She finally admitted that she thought he might learn something that would scare him, like the fact that our Sun might go supernova.

Now that’s an interesting concept-the possibility of our Sun blowing up as a frightening thing to an eight-year-old child. Most kids I know of that age are really INTO making explosive noises, and their cartoons are chock-full of such stuff. So, there had to be something more to this concern. In the course of our conversation, it became pretty clear that she didn’t want her child to be frightened by science and she was worried that astronomy might have too much violence for a young child.

Just to allay any concerned folks who may be reading this, the Sun isn’t going to go supernova. Its death is going to be more gentle, as star death goes, and it isn’t going to happen for five billion years or so. So, there’s not much to worry about in the near term, and certainly not for an eight-year-old.

I think what intrigued me about this mom’s concern was that her son would get scared of something like this simply by looking through a telescope at other stars. I did mention to her that looking at stars is normally something very enjoyable and thought-provoking. And, I did point out that looking at the Sun was NOT a good idea and I wouldn’t recommend it. I told her that the folks at the museum usually look at planets, especially since those are easy to find in light-polluted skies.

She decided that would be cool, so I guess one of these nights, her son will get to see some celestial delights through a big telescope. I can just about guarantee that he won’t be scared. But he might come home and want a telescope…

Black Holes Get No Respect

They’re SO Misunderstood

How many of you have seen ANY movie or read a bad science fiction story that featured a black hole that had people somehow flying into a black hole and managing to get out again? I remember this really awful movie from Disney called (imaginatively enough) “The Black Hole” that pretty much ignored most physical laws and violated more than a few storytelling rules. It seems like black holes suck more than gas and dust and stars into their maws. They also have the strange ability to remove a writer’s common sense when it comes to a) tellling a credible story, and b) respecting that black holes have rules they must follow and that you can’t bend those rules just so that the hero can get the girl in the end.

Let’s face it. If you’re in a spacecraft anywhere NEAR a black hole, you’re going to feel its effects. Its gravitational pull will tug at you. The radiation environment will kill you, unless your spacecraft is really well-shielded. And even then, there’s a good chance that you’re never going to father (or mother) children after the encounter (provided you survive it). If you happen to stray too close to the black hole, you’re toast. You’re going in and you’re going to be swirling down the celestial tidy bowl for a LONG time (from the perspective of an outside observer). From YOUR perspective, it’s going to be a short, nasty, brutish trip into the universe’s ultimate trash compactor. And, no matter how much a producer or writer or art director or second assistant key grip wants to see your spacecraft escape the black hole, it ain’t gonna happen. You won’t have a droid up there in the control booth trying to turn off the compactor at the last second. You. Are. Toast.

So, you might ask me if you’re one of those writers who just HAS to have a black hole in your show to keep the sponsors happy, what CAN be written about? IS there a viable, exciting story about these things that could hold an audience’s interest?

Of course I have an answer to that, mostly because I DID write such a story some years ago for a planetarium show. I had the spacecraft go not quite close enough to the singularity’s event horizon and the pilot pulled out just in time… but not before a few hair-raising, nail-biting moments when both the crew and the audience weren’t sure if they’d get out in time. I had twenty minutes to get them out TO the black hole’s vicinity (all the while explaining how we can detect these dudes), and then about five minutes to put them in danger and get them out again. By standards of a movie or network TV, that’s pretty short, but it kept me intellectually honest, and I told a good story with accurate science and emotional affect (as they like to say in the business).

So, it can be done. And black holes, if you respect them and what they’re about, can give you fodder for a LOT of good stories.
